Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display panel and a display device. Background Art

[0002] With the continuous development of network technology, more and more users need to perform account transactions and other operations on display devices. However, when users perform the above operations in public places, it is easy for personal information to be leaked when they access bank accounts, pay bills or enter personal information, which may lead to the risk of identity theft and privacy infringement. Therefore, display devices with anti-peeping function have received more and more attention.

[0003] For display panels, a grating structure is usually set on the light-emitting side of the display panel to form an anti-peeping film. The grating structure can block the light emitted from a wide viewing angle, thereby changing the wide viewing angle of the screen to a narrow viewing angle to achieve an anti-peeping function. However, after the grating structure is set in the display panel, the display panel can only be in the anti-peeping mode all the time. When multiple people need to watch the screen at the same time, it will cause inconvenience in use, thereby affecting the user experience. Summary of the invention

As an example, the intermediate dielectric layer 225 may include silicon nitride.

[0047] The interlayer dielectric layer 226 may be disposed on the intermediate dielectric layer 225 and the capacitor electrode layer C. The interlayer dielectric layer 226 may include a stacked structure composed of one or more inorganic materials such as silicon oxide, silicon nitride, and silicon oxynitride.

[0048] It can be understood that the driving substrate 200 includes a driving circuit, and the driving circuit is used to drive the light-emitting element to emit light 310. As an example, the driving circuit includes a pixel circuit, and the pixel circuit is electrically connected to the light-emitting element and is used to drive the light-emitting element 310 to emit light.

[0049] Optionally, the display panel 100 further includes a light emitting device layer 300 located on one side of the substrate 210 ; specifically, the light emitting device layer 300 is located on a side of the driving substrate 200 away from the substrate 210 .

[0050] The light emitting device layer includes a plurality of pixels SP.

[0051] Optionally, the light emitting device layer 300 includes a plurality of light emitting elements 310 forming pixels SP.

[0052] It can be understood that the pixel SP is formed by the light emitting element 310 , and therefore the boundary of the pixel SP in the embodiment of the present application can be defined by the light emitting element 310 .

[0053] Optionally, the pixel SP / light-emitting element 310 in the present application may be an organic light-emitting diode (OLED), or a micro light-emitting diode (Micro-LED) or a sub-millimeter light-emitting diode (Mini-LED).

[0054] Of course, the light-emitting elements in the device may include different types of light-emitting elements at the same time, or may include different types of light-emitting elements. For example, the main pixel SP1 and the auxiliary pixel SP2 may both be organic light-emitting diodes (OLED), or may be micro-LEDs or sub-millimeter light-emitting diodes (Mini-LEDs).

[0055] Optionally, the light emitting device layer 300 includes an anode layer 301 , an organic light emitting material 302 , and a cathode layer 303 which are sequentially arranged in a direction away from the substrate 210 and pointing toward the light emitting surface of the display panel 100 .

[0056] The light emitting device layer 300 further includes a pixel definition layer 340 located on a side of the anode layer 301 away from the driving substrate 200. The pixel definition layer 340 may be formed of an organic material such as polyimide (PI), polyamide, benzocyclobutene (BCB), acrylic resin or phenolic resin, or an inorganic material such as SiNx.

[0057] Optionally, the anode layer 310 includes a plurality of anode patterns corresponding to the pixels SP one by one, and the anode pattern in the anode layer 301 is connected to the source electrode or the drain electrode of the thin film transistor through a via hole. The pixel definition layer 340 is located on the side of the anode layer 301 away from the substrate 110 and includes a plurality of openings exposing the anode layer 301, and the pixel definition layer 340 covers the edge of the pattern of the anode layer 301. The organic light-emitting material 302 is at least partially filled in the opening of the pixel definition layer 340 and is in contact with the anode layer 301.

[0058] Optionally, the anode layer 301, the organic light-emitting material 302 and the cathode layer 303 defined by the opening of each pixel definition layer 340 constitute a light-emitting element 310. Different organic light-emitting materials 302 can emit light of different colors to form pixels SP of different colors, and multiple pixels SP display the picture together. It should be noted that the periphery of the pixel SP in the present application refers to the periphery of the light-emitting element 310, that is, when the structures described below are positioned by the periphery of the pixel SP, the boundary of the pixel SP is defined by the boundary of the light-emitting element 310, and the periphery of the light-emitting element 310 is the periphery of the pixel SP. In other words, the area where the pixel SP is located can be the area where the opening of the pixel definition layer 340 that accommodates the light-emitting element 310 is located, the boundary of the pixel SP is the boundary of the opening of the pixel definition layer 340, and the periphery of the pixel SP is the periphery of the opening of the pixel definition layer 340.

[0059] Furthermore, the pixels SP of the display panel 100 include at least two types of pixels, including primary pixels SP1 and auxiliary pixels SP2 .

[0060] Optionally, the auxiliary pixel SP2 is located around the main pixel SP1.

[0061] Optionally, the auxiliary pixel SP2 is located between adjacent primary pixels SP1.

[0062] Optionally, the display panel 100 further includes an encapsulation layer 400 located on the light emitting device layer 300; the encapsulation layer 400 completely covers the light emitting device layer 300 to seal the light emitting device layer 300. It is understandable that the "on" mentioned in this embodiment can be understood as being located on the "side away from the substrate".

[0063] Optionally, the encapsulation layer 400 is a thin film encapsulation layer, which is located on the cathode layer 303 and includes a first inorganic encapsulation layer, a first organic encapsulation layer, and a second inorganic encapsulation layer sequentially arranged in a direction away from the substrate 210. Of course, in other optional embodiments of the present invention, the encapsulation layer may include any number of stacked organic materials and inorganic materials as required, but at least one layer of organic material and at least one layer of inorganic material are alternately deposited, and the bottom layer and the top layer are composed of inorganic materials.

[0064] Optionally, the display panel further includes an auxiliary functional layer 600, the auxiliary functional layer 600 is located on the side of the light emitting device layer 300 facing the display surface of the display panel 100; that is, the auxiliary functional layer 600 is located on the side of the light emitting device layer 300 away from the substrate 210.

[0065] Optionally, the auxiliary function layer 600 is located on a side of the encapsulation layer 400 away from the light-emitting device layer 300 .

[0066] Optionally, the auxiliary functional layer 600 includes a first functional portion 610 , and the first functional portion 610 is provided corresponding to the auxiliary pixel SP2 .

[0067] It should be noted that the first functional portion 610 corresponds to the auxiliary pixel SP2, which means that the first functional portion 610 is located directly above the auxiliary pixel SP2, and in a direction perpendicular to the plane of the substrate 210, that is, the third direction Z, the first functional portion 610 at least partially overlaps with the auxiliary pixel SP2.

[0068] Optionally, the projection of the first functional portion 610 in the third direction Z covers the projection of the auxiliary pixel SP2 in the third direction Z.

[0069] When the auxiliary pixel SP2 is located around the main pixel SP1 , the main pixel SP1 is disposed away from the first functional portion 610 , that is, the first functional portion 610 is located obliquely above the main pixel SP1 .

[0070] Optionally, in the first state, at least a portion of the first functional portion 610 is light-shielded.

[0071] like Figure 4 and Figure 5 As shown, Figure 4 for Figure 3 A schematic diagram of light in the second state of the embodiment shown; Figure 5 for Figure 3 The illustrated embodiment is a schematic diagram of light in the first state.

[0072] Optionally, in the first state, since the first functional portion 610 shields light, the main pixel SP1 exposed by the first light shielding portion 610 can be used as the main device for the display panel to perform light-emitting display. In addition, the auxiliary pixel SP2 arranged around the main pixel SP1 is covered by the first functional portion 610, and the light emitted by the first functional portion 610 will not be seen at a normal viewing angle of the display panel. The normal viewing angle may be a normal viewing angle or a viewing angle substantially directed to the display panel.

[0073] Moreover, in the first state, the first functional portion 610 and its surrounding area that are transformed into the light-shielding state can form an anti-peeping mode. Specifically, at a positive viewing angle and a small viewing angle, the small-angle light L1 emitted by the main pixel SP1 will not be blocked by the first functional portion 610 in its oblique direction, and can therefore be viewed. However, the small-angle light L2 emitted by the auxiliary pixel SP2 is blocked by the first functional portion 610 and cannot be viewed. At a large viewing angle, when the large-angle light L1' emitted by the main pixel SP1 is blocked by the first functional portion 610 in its oblique direction and cannot be viewed, the large-angle light L2' emitted by the auxiliary pixel SP2 can be viewed from an oblique direction through the opening portion in the first functional portion 610. Then, the viewer at a large viewing angle can only see the interfering light emitted by the auxiliary pixel SP2. Therefore, the display panel provided in the embodiment of the present application can achieve an anti-peeping effect, thereby well protecting the privacy of the user.

[0074] Optionally, the display panel also includes a second state; in the first state, the electrochromic material is in a light-shielding state; in the second state, the electrochromic material is in a transparent state.

[0075] Optionally, the first state is an anti-peeping mode, and the second state is a normal mode.

[0076] In the second state, the electrochromic material is transparent, so the small-angle light L2 emitted by the auxiliary pixel SP2 will not be blocked by the first functional part 610 and can be viewed. The large-angle light L1' emitted by the main pixel SP1 will not be blocked by the first functional part 610 in its oblique direction, so it can also be viewed. Therefore, the display at the normal viewing angle and the display at the large viewing angle both involve the auxiliary pixels and the main pixels.

[0077] With such a design, the display panel can have at least two viewing angles. Moreover, since the display at the normal viewing angle and the display at the wide viewing angle both involve the auxiliary pixels and the main pixels, the uniformity of the display effect at each viewing angle in the second state can be improved.

[0078] It should be noted that the first state and the second state mentioned in this application do not only mean that the entire display panel is in the anti-peeping mode, but can be a partial anti-peeping state. In other words, the first state and the second state can be understood as the light-transmitting state of the electrochromic material. It controls whether the corresponding display panel area is in the normal mode or the anti-peeping mode. This will be explained in detail below and will not be repeated here.

[0079] Optionally, in some other optional embodiments of the present application, it is possible to further control whether the auxiliary pixel is lit to match the state of the first functional layer, thereby further improving the anti-peeping related. Optionally, in the first state, the main pixel SP1 emits light, the auxiliary pixel SP2 does not emit light; the electrochromic luminescent material is in a light-shielding state. In the second state, the main pixel SP1 emits light, the auxiliary pixel SP2 emits light; the electrochromic luminescent material is in a light-shielding state.

[0080] Optionally, in one embodiment, the first functional portion 610 includes an electrochromic material.

[0081] Specifically, the first functional part 610 includes a control electrode layer 610 located on at least one side of the electrochromic material; the control electrode layer 610 includes a first control electrode layer 610-1 and a second control electrode layer 610-2 located on both sides of the electrochromic material in a direction perpendicular to the display panel 100, that is, in the third direction Z. It can be understood that in the normal mode, the control electrode layer 610 is not applied with a voltage, and the electrochromic material is in a transparent state; when in the anti-peeping mode, at least part of the control electrode layer 610 is applied with a voltage, and the transmittance of the electrochromic material corresponding to the control electrode layer 610 applied with a voltage changes and turns into a light-shielding state. The light-shielding state includes a black state or a gray state.

[0082] Optionally, the electrochromic material includes an ion storage layer, an electrolyte layer and a color-changing material layer. The electrochromic material includes tungsten oxide (WO3), which can be switched between a transparent state and a light-shielding state.

[0083] Optionally, the display panel 100 further includes a cover plate 800 located on the auxiliary function layer 600. The cover plate 800 may be a glass material or a flexible protective film layer. Optionally, in some optional embodiments of the present application, the display panel 100 further includes a polarizing layer 810 located under the cover plate 800, and the polarizing layer 810 may include a circular polarizer.

[0084] Optionally, the display panel 100 also includes a second flat layer 700 located on the auxiliary function layer 600. Specifically, the second flat layer 700 is located between the auxiliary function layer 600 and the cover plate 800, or between the auxiliary function layer 600 and the polarizing layer 810. The second flat layer 700 may cover the auxiliary function layer 600. Optionally, the second flat layer 700 is an organic film layer having a certain thickness. Since the first functional part in the present application needs to be specifically set on different auxiliary pixels, and in order to achieve the partitioned or angled prevention and control described below, some of the first functional parts are spaced apart, so the first functional part has a targeted patterned design, and the second flat layer 700 provided in this embodiment can provide a uniform and flat bearing surface for the setting of the polarizing layer 810 or the cover plate 800.

[0085] Please continue to refer to Figure 2-Figure 3 As shown, optionally, at least two main pixels of different colors are cyclically and alternately arranged in the first direction X and / or the second direction Y to form a main pixel array; the auxiliary pixels are located between adjacent main pixels in the first direction X or the second direction Y;

[0086] The first direction X and the second direction Y intersect.

[0087] Through such a design, adjacent main pixels can share the interference light of auxiliary pixels for anti-peeping function. This can improve the utilization rate of auxiliary pixels. On the one hand, it improves the light utilization rate of auxiliary pixels and reduces power consumption. On the other hand, it optimizes the arrangement of main pixels and auxiliary pixels, reduces the proportion of auxiliary pixels, and saves space on the display panel.

[0088] It should be noted that the first direction X and the second direction Y are both parallel to the plane where the display panel is located. Optionally, the first direction X and the second direction Y are perpendicular.

[0089] Optional, such as Figure 2 and Figure 3 As shown, the display panel 100 includes main pixels SP1 of three colors. In the first direction X, the main pixels of the first color and the second color are arranged alternately in a cycle, or the main pixels of the first color and the third color are arranged alternately in a cycle. The main pixels SP1 of the first color are adjacent to the main pixels SP1 of the second color on two opposite sides in the first direction X, and the main pixels of the third color are adjacent to two opposite sides in the second direction Y.

[0090] Specifically, the display panel 100 includes main pixels SP1 of three colors: red, green, and blue. In the first direction X, the blue main pixels and the green main pixels are arranged alternately in a cycle, or the red main pixels and the green main pixels are arranged alternately in a cycle. The red main pixels are arranged adjacent to the green main pixels on two opposite sides in the first direction X, and the blue main pixels are arranged adjacent to the two opposite sides in the second direction Y.

[0091] In some embodiments of the present application, optionally, the auxiliary pixel SP2 is a white light pixel.

[0092] With such a design, since the interference degree of white light pixels on pixels of other colors is uniform, the interference degree of main pixels of various colors can be made similar under a wide viewing angle, thereby improving the uniformity of display and anti-peeping.

[0093] Optionally, an auxiliary pixel SP2 is set between two adjacent main pixels SP1. That is, two adjacent main pixels SP1 share the auxiliary pixel SP2 between them. In other words, main pixels of different colors share a white light auxiliary pixel. Because the light emitted by the white light main pixel includes components of the same color as the light emitted by pixels of the other three colors, the interference effect is more uniform in the first state; in the second state, it can better cooperate with the main pixel to emit light without excessively disrupting the rendering effect between main pixels of different colors. In particular, for the main pixel arrangement of the above embodiment, by setting an auxiliary pixel that emits white light, the rendering effect of the main pixel can be guaranteed when the auxiliary pixel participates in conventional display, thereby improving the PPI of the display panel with anti-peeping function to a certain extent, and at the same time improving the anti-peeping effect.

[0094] Optionally, the green primary pixel has the smallest corresponding area, that is, the area of ​​the blue primary pixel is larger than the green primary pixel; and the area of ​​the red primary pixel is larger than the green primary pixel.

[0095] Optionally, in some optional embodiments, the auxiliary pixels may directly use light-emitting elements that emit white light.

[0096] Of course, in some optional other embodiments, a blue light emitting element can be superimposed with a color conversion layer to form an auxiliary pixel, so that the auxiliary pixel can emit white light. For example: the auxiliary pixel includes a blue light emitting element superimposed with a quantum dot film; or a blue light emitting element superimposed with a phosphor layer;

[0097] Optionally, in some other optional embodiments, the auxiliary pixel emitting white light may be a pixel formed by stacking or combining light emitting elements of three colors: red, green and blue.

[0098] For example, light emitting elements or light emitting materials of three colors are stacked in the third direction Z, that is, stacked RGB three-color light emitting elements.

[0099] For another example, the auxiliary pixel is adjacently arranged RGB three-color light emitting elements, that is, a combined RGB three-color light emitting element.

[0100] Optionally, the auxiliary pixel is a white light pixel synthesized by adjacently arranged RGB microLED light-emitting elements. In this way, the three-color microLED can be set to the position of the auxiliary pixel by direct transfer, which can not only realize the auxiliary pixel to emit white light, but also reduce the space occupied by the three-color pixel. Optionally, the three-color microLED can be set on the electrode of the same auxiliary pixel by direct transfer.

[0101] In some embodiments of the present application, Figure 6 and Figure 7 As shown, Figure 6 and Figure 7 They are two other partial enlarged top views of the display panel provided by the embodiments of the present invention.

[0102] Optionally, in the first state, at least a portion of the first functional portion 610 is transparent.

[0103] Such a design can enable the display panel to be protected from peeping at a specific viewing angle, or a local display area to be protected from peeping.

[0104] Optional, such as Figure 6 As shown, when the display panel area is partially protected from peeping, it means that at least part of the display area is in the anti-peeping mode, and at least part of the display area is in the normal mode; here, the area that needs to be in the anti-peeping mode is referred to as area A, and the area that needs to be in the normal mode is referred to as area B.

[0105] In the A region, no voltage is applied between the first control electrode layer 610-1 and the second control electrode layer 610-2 on both sides of the electrochromic material of all the first functional parts 610, or the voltage difference between them is greater than 0V, so that the first functional part is in the first state, so that the area where the first functional part is located in the first state, that is, the A region, is converted to the anti-peeping mode. For the B region, no voltage is applied between the first control electrode layer 610-1 and the second control electrode layer 610-2 on both sides of the electrochromic material of all the first functional parts 610, or the voltage difference between them is 0V, so that the first functional part is in the second state, so that the area where the first functional part is located in the second state, that is, the B region, is in the normal mode for display. For example, the A region is the display area for password input or presentation, and the B region is the non-privacy information display area.

[0106] Of course, in some scenarios, since the viewer cannot look directly at the display area, it is hoped that the display area has a specific direction of anti-peeping. For example, in a car display, the central display screen is neither facing the driver's seat nor the co-pilot seat. At this time, in order to prevent the display image from affecting the driver, or the displayed content is confidential information, it is hoped that the display image can only be seen by one of them.

[0107] Optional, such as Figure 7 and Figure 8 As shown, Figure 8 For along Figure 7 A partial cross-sectional view along the BB direction, the cross-section is perpendicular to the plane where the display panel is located. Optionally, for an area where privacy protection at a specific angle is required, the first functional portion 610 in the direction where privacy protection is required corresponding to the main pixel presents a first state, that is, the electrochromic material in the viewing angle direction is in a light-shielding state. The first functional portion 610 in the direction where privacy protection is not required presents a second state, that is, the electrochromic material in the viewing angle direction is in a light-transmitting state.

[0108] Optionally, auxiliary pixels SP2 are arranged in at least two directions of at least one main pixel SP1.

[0109] In this way, the display panel can achieve selective privacy protection in at least two viewing directions.

[0110] Of course, the present application is not limited to the viewing angle protection in two viewing directions, that is, at least one main pixel SP1 can set the auxiliary pixel SP2 in three directions, four directions, or N directions. The direction mentioned here refers to the orientation of the auxiliary pixel relative to the main pixel when setting the auxiliary pixel, and the direction is parallel to the plane where the display panel is located.

[0111] Optionally, an auxiliary pixel SP2 is disposed between two adjacent primary pixels SP1, that is, the two adjacent primary pixels SP1 share the auxiliary pixel SP2 therebetween.

[0112] In this case, one of the two main pixels that share the auxiliary pixel is the first main pixel. When anti-peeping display is required at a specific angle, the state of the first functional unit is selected based on the first main pixel. That is, when anti-peeping display is required in the first direction and normal display is required in the second direction, the first functional unit corresponding to the auxiliary pixel adjacent to the first main pixel in the first direction is in the first state; the first functional unit corresponding to the auxiliary pixel adjacent to the first main pixel in the second direction is in the second state.

[0113] Optionally, in the anti-peeping mode in a specific direction, the first auxiliary portion of the side of the first main pixel that needs to be anti-peeping is in a first state, that is, a light-shielding state.

[0114] Optionally, in the full-angle anti-peeping mode, the first auxiliary parts on each side of the first main pixel that needs to be anti-peeping are in a first state, that is, a light-shielding state.

[0115] Optionally, the display panel includes main pixels of three colors: red, green, and blue, wherein the green main pixel has the smallest corresponding area, and in the first direction X, the blue main pixels and the green main pixels are arranged alternately in a cycle, or the red main pixels and the green main pixels are arranged alternately in a cycle. The red main pixels are arranged adjacent to the green main pixels on two opposite sides in the first direction X, and the blue main pixels are arranged adjacent to the two opposite sides in the second direction Y.

[0116] Furthermore, the green primary pixel is the first primary pixel, for example Figure 8As shown, taking the green main pixel as the standard, when the right-angle peeping protection is required, the first functional part corresponding to the auxiliary pixel on the right side of the green main pixel is light-shielding, and the first functional part corresponding to the auxiliary pixel on the left side of the green main pixel is light-transmissive. In this way, the green main pixel can emit light toward the left side at a large angle of view, while the light toward the right side at a large angle of view will be blocked by the first functional part on the right, and the light emitted from the auxiliary pixel on the right side at a normal angle of view will also be blocked by the first functional part; and the right angle of view will also be affected by the large-angle interference light emitted by the auxiliary pixel on the left side of the green main pixel, such as light L2'.

[0117] Optionally, the green main pixel as the first main pixel has the smallest corresponding area, that is, the area of ​​the blue main pixel is larger than the green main pixel; the area of ​​the red main pixel is larger than the green main pixel; this can further improve the anti-peeping effect.

[0118] Please continue to refer to Figure 2-Figure 3 , Figure 6 or Figure 7-8 As shown in the embodiments corresponding to any of the figures, optionally, a plurality of auxiliary pixels SP2 are arranged at intervals around the main pixel SP1.

[0119] The inventors have found that since auxiliary pixels also require an evaporation mask for evaporation, by designing the auxiliary pixels surrounding the main pixels as multiple intervals, a non-closed annular evaporation mask can be used, which reduces the process difficulty. In addition, the uniformity of anti-peeping at all angles is taken into account.

[0120] Optionally, at least two auxiliary pixels SP2 are located on the same side of the same main pixel SP1 and are arranged along the extension direction of the edge of the same main pixel SP1. In this way, the anti-peeping effect can be made more uniform while taking into account the process difficulty.

[0121] Further, in combination with the above-mentioned drawings Fig. 9 As shown, Fig. 9 A partial enlarged top view of a display panel provided in the present application.

[0122] Optionally, a plurality of auxiliary pixels SP2 are arranged around a primary pixel SP1 at intervals; and a plurality of auxiliary pixels SP2 corresponding to the same primary pixel SP1 form an auxiliary pixel group, and the auxiliary pixels SP2 in the same auxiliary pixel group share a driving circuit.

[0123] Furthermore, a plurality of auxiliary pixels SP2 corresponding to the same primary pixel SP1 form an auxiliary pixel group, and the auxiliary pixels SP2 in the auxiliary pixel group correspond to the same first functional portion 610 .

[0124] Through such a design, the difficulty of patterning can be reduced, the process can be simplified, the display panel space can be better utilized, the cost can be reduced, and the anti-peeping and display effects can be taken into account at the same time.

[0125] In some embodiments of the present application, Fig.10 As shown, Fig.10 For along Figure 2 Local cross-section along the AA direction, or along Figure 7 The partial cross-sectional view along the BB direction is a cross-sectional view of some other optional embodiments of the present application, and the cross-sectional view is perpendicular to the plane where the display panel is located. The cross-sectional views of the following embodiments of the present application can all be understood by referring to the above description, and will not be repeated below.

[0126] Optionally, the size of the first functional portion 610 is larger than the size of the auxiliary pixel SP2.

[0127] Optionally, the width D1 of the first functional portion 610 is greater than the width D2 of the auxiliary pixel SP2. Optionally, the width direction is the direction of the connection line of the main pixels on both sides of the auxiliary pixel, for example Fig.10 As shown, the width here can be the dimension in the first direction X.

[0128] Optionally, the projection area of ​​the first functional portion 610 in the third direction Z is greater than the projection area of ​​the auxiliary pixel SP2 in the third direction Z.

[0129] Further, the projection of the first functional portion 610 in the third direction Z covers the projection of the auxiliary pixel SP2 in the third direction Z.

[0130] It should be noted that the viewing angle of the present application refers to the angle between the viewer's position and the center normal direction of the display panel (i.e., the normal passing through the center of the display panel and perpendicular to the surface where the display panel is located). When the angle is substantially 0°, it can be understood as a positive viewing angle; when the angle is less than the minimum anti-peeping angle, it can be understood as a small viewing angle; when the angle is equal to or greater than the minimum anti-peeping angle, it can be understood as a large viewing angle. The minimum anti-peeping angle is determined according to demand.

[0131] Optionally, the first functional portion 610 and the auxiliary pixel SP2 are directly opposite to each other in the third direction Z, that is, in a cross section parallel to the third direction Z and parallel to the first direction X or the second direction Y, the center of the first functional portion is directly opposite to the center of the auxiliary pixel, so as to avoid any inclination between the two, thereby avoiding affecting the display effect in the wide viewing angle display mode.

[0132] Optionally, the shape of the first functional portion 610 is similar to the shape of the corresponding auxiliary pixel SP2. That is, in a pair of the first functional portion and the auxiliary pixel, the first functional portion is a proportionally enlarged figure of the auxiliary pixel. The shape mentioned here can be understood as a positive projection figure on the plane where the display panel is located along the third direction Z. In this way, the amount of interference light emitted by the auxiliary pixel in all directions can be ensured to be uniform, thereby improving the uniformity of anti-peeping.

[0133] Please continue to refer to Fig.10 As shown, the display panel 100 satisfies the formula: W = 2 × H × tanθ;

[0134] Wherein, W is the distance between adjacent first functional parts; H is the distance from the light-emitting device layer to the top of the first functional part; θ is the anti-peeping angle.

[0135] Optionally, W is a distance parallel to the first direction X; that is, a distance in a direction of main pixel connection lines on both sides of the first functional portion.

[0136] Optionally, the anti-peeping angle may be a minimum anti-peeping angle, and the minimum anti-peeping angle may be determined according to requirements.

[0137] Optionally, H is the distance from the top of the pixel definition layer 340 to the top of the first functional part; the top of a structure mentioned here is the surface of the structure facing away from the substrate. Through such a design, the anti-peeping effect can be improved in just one step.

[0138] Please refer to Figures 11 to 13 As shown, Figure 11 to Figure 13 They are respectively cross-sectional views of the display panel provided in the present application.

[0139] Optionally, the display panel 100 further includes a color resist layer 900 , and the color resist layer 900 is located on a side of the light emitting device layer 300 away from the substrate 210 .

[0140] With such a design, at least one circular polarizer can be saved, the overall power consumption of the display panel can be reduced, the transmittance of the display panel can be increased, and the display effect of the display panel can be improved. In other words, optionally, the cover plate 800 is directly disposed on the second flat layer 700 .

[0141] Through such a design, the anti-peeping effect and display effect can be further optimized.

[0142] Optional, such as Figure 11 to Figure 13 As shown, the color resist layer 900 includes a main color resist portion 910 , and the main color resist portion 910 corresponds to the main pixel SP1 .

[0143] It should be noted that the main color resist portion 910 corresponds to the main pixel SP1, which means that the main color resist portion 910 is located directly above the main pixel SP1. In other words, the projection of the main color resist portion 910 in the third direction Z covers the projection of the main pixel SP1 in the third direction Z.

[0144] Furthermore, in combination with the auxiliary pixel SP2 being a white light pixel, the white light emitted by the auxiliary pixel can still interfere with the display content at a wide viewing angle, and due to the filtering of the main color blocking portion, the wide-viewing angle light emitted by the auxiliary pixel can be consistent with the color of the corresponding main pixel that needs to be interfered with, thereby better forming color-contrast interference; especially in the case where main pixels of different colors share the auxiliary pixel, the auxiliary pixel of one color (that is, the auxiliary pixel is a white light pixel) can specifically emit wide-viewing angle light of the corresponding color to the main pixels of different colors on different sides of it, thereby more specifically interfering with pixels of different colors at a wide viewing angle, thereby further improving the anti-peeping effect.

[0145] Optional, such as Fig.13 As shown, the color resist layer 900 includes an auxiliary color resist portion 920 , and the auxiliary color resist portion 920 corresponds to the auxiliary pixel SP2 .

[0146] It should be noted that the auxiliary color resist portion 920 corresponds to the auxiliary pixel SP2, which means that the auxiliary color resist portion 920 is located directly above the auxiliary pixel SP2. That is, the projection of the auxiliary color resist portion 920 in the third direction Z covers the projection of the auxiliary pixel SP2 in the third direction Z.

[0147] Through this color design, in normal display, the auxiliary pixels can also be displayed as pixels with specific colors to increase the display PPI. At the same time, it can also provide interference light of other colors in anti-peeping mode.

[0148] Optionally, the color of the auxiliary color resist portion 920 is different from the color of the adjacent primary pixel SP1. Through this embodiment, color crosstalk in the normal mode can be avoided; the auxiliary color resist portion 920 can also be used to further filter the large-angle light emission of the primary pixel SP1 in the anti-peeping mode to improve the anti-peeping effect. In addition, in the normal mode, the auxiliary pixel can also be rendered with the primary pixel to improve the display effect.

[0149] Further, in this embodiment, the pixel arrangement rule is: along the first direction X, the main pixels SP1 of the three colors of RGB are arranged alternately in a cycle, that is, the arrangement order is ...-RGBRGB-...; along the second direction Y, the main pixels SP1 of the same color are arranged adjacent to each other, that is, the main pixels SP1 in the same row on the second direction Y are the main pixels SP1 of the same color. The auxiliary pixel SP2 is located between two adjacent main pixels SP1 of different colors in the first direction X. In this way, the auxiliary pixel and the main pixel together still form a color cycle arrangement of RGB in the first direction X.

[0150] Through this embodiment, the pixel arrangement is combined with the auxiliary color resist portion 920 correspondingly set on the auxiliary pixel SP2. In the anti-peeping mode, the auxiliary color resist portion 920 is used to further filter the wide-angle light emission of the main pixel SP1. The display panel 100 can also have an anti-peeping function while maintaining a better rendering effect in the normal mode while improving the PPI, thereby further improving the anti-peeping and display effects.

[0151] Optionally, in this embodiment, the auxiliary color resist portion 920 is located on a side of the first functional portion 610 facing away from the substrate 210 , and has the same outline and area as the first functional portion 610 .

[0152] Optionally, the auxiliary color resist portion 920 and the first functional portion 610 are disposed adjacent to each other in the third direction Z, and their projections in the third direction Z overlap.

[0153] In other optional embodiments of the present application, the auxiliary color resist portion 920 may be located between the first functional portion 610 and the light emitting element 310 .

[0154] like Figure 12 to Figure 14 As shown, Fig.14 This is a cross-sectional view of another display panel provided in the present application.

[0155] The similarities between this embodiment and the above embodiment will not be repeated; the difference is that the display panel 100 further includes a touch function layer 500 , and the touch function layer 500 is located on a side of the light emitting device layer 300 away from the substrate 210 .

[0156] Optionally, the touch function layer 500 includes at least one touch electrode layer, and the at least one touch electrode layer is located on a side of the first function portion 610 away from the substrate 210 .

[0158] Optionally, the touch electrode layer may be made of transparent ITO material. Furthermore, at least part of the touch electrode overlaps with the pixel SP. With such a design, on the one hand, the auxiliary function layer can be added while increasing the touch area to take into account the touch performance. On the other hand, the touch function layer can be prevented from blocking the main pixel and the auxiliary pixel, thereby ensuring the touch effect while taking into account the display effect.

[0159] like Fig.14 As shown, optionally, the touch function layer 500 is located on the encapsulation layer 400 of the display panel 100 , that is, the touch function layer 500 is located on a side of the encapsulation layer 400 away from the light emitting element 310 .

[0160] Optionally, the touch function layer 500 includes at least one touch electrode layer 510, and the first functional part 600 also includes a control electrode layer 610 located on at least one side of the electrochromic material, and at least one touch electrode layer 510 is in the same layer as the control electrode layer 610; that is, the control electrode layer 610 is in the same layer and made of the same material as one or more film layers in the touch function layer 500.

[0161] Combination Fig.14 Figure and Fig.15 As shown, Fig.15 The schematic top view of a touch electrode layer in a touch function layer of a display panel provided in an embodiment of the present application is as follows. The similarities between this embodiment and the above embodiment are not repeated; the difference is that the touch electrode layer 510 includes a first touch conductive layer 521 and a second touch conductive layer 522 .

[0162] Optionally, the control electrode layer 610 includes a first control electrode layer 610-1 and a second control electrode layer 610-2 located on both sides of the electrochromic material in a direction perpendicular to the display panel, i.e., in a third direction Z; the first control electrode layer 610-1 is in the same layer and made of the same material as the first touch conductive layer 521; and / or the second control electrode layer 610-2 is in the same layer and made of the same material as the second touch conductive layer 522.

[0163] Through such a design, the film layers can be reduced, so that the display panel can have more functions and the thickness of the display panel can be reduced.

[0164] Optionally, in some optional embodiments of the present application, the display panel 100 further includes a covering layer 820 located under the cover plate 800. Optionally, the covering layer 820 may be formed on the auxiliary function layer 600 and the cover plate 800. Optionally, the covering layer 820 may be formed on the touch electrode layer 510 of the touch function layer 500 and the cover plate 800, and at least part of the electrode layer in the touch electrode layer 510 may be adjacent to the covering layer 820, or the covering layer 820 may be formed as a carrier film layer and then bonded to the display panel body.

[0165] It should be noted that, optionally, the first touch conductive layer 521 and the second touch conductive layer 522 may be an electrode layer and a bridge layer, respectively. In this embodiment, the film layer where the electrode layer is located is the first touch conductive layer 521, and the film layer where the bridge layer is located is the second touch conductive layer 522. In other optional embodiments of the present application, the film layer where the electrode layer is located is the second touch conductive layer 522; and the film layer where the bridge layer is located is the first touch conductive layer 521.

[0166] In addition, in other technical solutions corresponding to this embodiment, the touch function layer 500 may include only one touch electrode layer. Optionally, when the touch function layer 500 includes only one touch electrode layer, the touch electrodes included therein are in self-capacitance mode.

[0167] Optionally, the touch electrode layer 510 is a metal grid structure.

[0170] Through the embodiments of the present application, the touch electrode is set at the same layer as the control electrode in the first functional part. On the one hand, the touch electrode can be made according to the process of the control electrode in the first functional part, saving film layers and reducing costs. On the other hand, since the film layer of the touch electrode is raised to the level where the first functional part is located, the touch electrode made of metal can be reused to further improve the anti-peeping effect.

[0171] In particular, when the touch electrode made of metal material is set in the same layer as the first control electrode layer, the wide-angle reflected light of the touch electrode made of metal material can be blocked by the first functional part in the anti-peeping mode, so as to avoid the wide-angle reflected light of the metal in the anti-peeping mode being particularly obvious, further improve the anti-peeping effect, and reduce the difference in the reflected light of the touch metal in the anti-peeping mode and the non-anti-peeping mode.

[0172] like Figures 16 to 22 As shown, Figures 16 to 18 , Figure 21 to Figure 22 They are cross-sectional views of the display panel provided in this application. Fig.21 and Fig. 22 It also includes light schematic diagrams of the display panel in two states.

[0174] Optional, such as Fig.16 and Fig.17 As shown, the second functional portion 620 overlaps with the first functional portion 610 .

[0175] Optionally, the second functional portion 620 and the first functional portion 610 are disposed adjacent to each other in the third direction Z, and their projections in the third direction Z overlap.

[0176] Optional, such as Fig.16As shown, the second functional portion 620 is located on a side of the first functional portion 610 facing away from the substrate 210 , and has the same outline and area as the first functional portion 610 .

[0177] Optional, such as Fig.17 As shown, the second functional part 620 is located on the side of the first functional part 610 facing the substrate 210, and has the same contour and area as the first functional part 610. In this way, the display panel can have an anti-peeping function, and the size of the anti-peeping viewing angle can be adjusted through the first functional part.

[0178] Optionally, in some embodiments of the present application, the second functional portion 620 is located on at least one side wall of the first functional portion 610. That is, the second functional portion 620 and the first functional portion 610 are adjacently disposed in a direction parallel to the plane where the display panel 100 is located.

[0179] Optional, please refer to Figure 18 to Figure 20 As shown, the second functional portion 620 is located on at least two sides of the first functional portion 610 , and the first functional portion 610 is directly opposite to the auxiliary pixel SP2 .

[0180] Optionally, the second functional portion 620 is symmetrically arranged with respect to the first functional portion 610 , or is arranged around the first functional portion 610 .

[0181] Specifically, Fig.19 As shown, the second functional portion 620 is located on both sides of the first functional portion 610 in the width direction; or, located on both sides of the first functional portion 610 in the direction of the main pixel SP1 connection; or, located between the first functional portion 610 and the main pixel SP1. The positional relationship description here can be understood as the positional relationship between the projections of the main pixel SP1 and the first functional portion 610 and the second functional portion 620 on the plane where the display panel is located.

[0182] Optionally, in combination with the top view, the second functional portion 620 is designed at least on one side of the length edge of the first functional portion 610 corresponding to the auxiliary pixel SP2.

[0183] Through the above embodiments, on the one hand, the anti-peeping effect of the second functional part can be further improved, and on the other hand, sufficient space can be provided for the arrangement of the second functional part.

[0184] Optional, such as Fig. 20 As shown, the second functional part 620 is arranged around the first functional part 610, which is equivalent to the first functional part 610 being located in the opening formed by the second functional part 620. This not only enables the second functional part to further improve the anti-peeping effect, but also improves the anti-peeping uniformity in all directions.

[0185] Please refer to Fig.21 and Fig. 22As shown, optionally, the second functional portion 620 is located in at least one opening of the first functional portion 610. That is, the first functional portion 610 is arranged around the second functional portion 620. Through such a design, the display panel can have different degrees of anti-peeping viewing angles. Specifically, as Fig.21 As shown, the first functional part 610 is in the second state, i.e., the light-transmitting state. At this time, the medium-angle light between the wide angle and the normal angle emitted by the main pixel can pass through the first functional part, while the wide-angle light will be blocked by the second functional part 620, so a wide-angle anti-peeping mode can be presented. Fig. 22 As shown, the first functional portion 610 is in a first state, i.e., a light shielding state. At this time, the light emitted by the main pixel between the wide viewing angle and the medium viewing angle will be blocked by the first functional portion 610 and the second functional portion 620, so that a medium viewing angle anti-peeping mode can be presented.

[0186] Of course, in some embodiments of the present application, such as Fig.23 and Fig.24 As shown, Fig.23 and Fig.24 The cross-sectional views of the display panels provided in the present application are respectively included, which also include a schematic diagram of the light of the display panel. Optionally, the second functional portion 620 may also be an electrochromic material. Among them, the similarities between the second functional portion 620 and the first functional portion 610 are not repeated. Differently, when a normal mode display is required, the second functional portion 620 and the first functional portion 610 located between the main pixels can both present a second state, that is, a light-transmitting state. When an anti-peeping mode display is required, one or more of the second functional portion 620 and the first functional portion 610 located in the same main pixel interval can be selected as needed to present a first state, that is, a light-shielding state. In this way, the unevenness can realize anti-peeping and normal modes, or select the size of the anti-peeping viewing angle. Different anti-peeping angles can be achieved according to the combination of different states of the second functional portion 620 and the first functional portion 610.
